陽光が差し込むサンゴ礁を泳ぐアオウミガメ

An ultra-realistic underwater photograph captures a majestic green sea turtle gliding effortlessly through a pristine, sunlit coral reef. Dramatic shafts of sunlight pierce the crystal-clear turquoise water, creating shimmering caustic patterns on the turtle's weathered shell and the sandy seabed below. The turtle, positioned off-center with ample lead room, is in razor-sharp focus, revealing the intricate texture of its skin and eye. A vibrant school of tiny orange anthias fish swarms in the mid-ground, while the complex, bumpy structures of brain and staghorn coral frame the lower third of the scene. A shallow depth of field renders the distant parts of the reef in a soft, beautiful blur, creating a serene and awe-inspiring mood of thriving marine life.
